Subject: [PATCH] Run IBCMerge on Linux build (dotnet/corefx#36763)

* Restores IBC data for both Linux and Windows on all platforms
* Chooses the right IBC data based on the target OS
* When target OS isn't anything specific (like, e.g. System.Linq and other assemblies that are not OS specific), embeds Windows IBC data
